I agree for the floppy removal.
Probably we could remove too usb-fdd and usb-hdd separate images and instead create an isohybrid capable image.

The 3 different format for usb boot (hdd, fdd, zip) may have been needed at a time when usb booting was new and a bios had a bug to understand one of the different acceptable formats.

I had one machine that only understand one format when I tested initially but after a bios upgrade, I was able to use any of the 3 format if I remember well.

Actually just using isohybrid should work fine (this should be what debian already do on current release).

That would allow to supply only one image that should work both for CD and usb booting in almost every x86 machine.
isohybrid is a trick that support in one image both the iso format and usb-hdd to boot.

isohybrid may have issue with a very small number of bios (those that only work with fdd or zip image).
An example could be https://bugs.archlinux.org/task/32189

This may be a problem if a bios update that fix the boot issue is not available. So probably don't remove yet the various usb- images creation, just let not run that script actually by default, do not distribute any usb image by default so we can see how many time this really happen.
